The embodiment of my invention illustrated is,

as stated, a machine for making wire garment hangers.

The frame or pedestal I is of such design as to provide a rigid foundation and support for the various parts, the bed 2 being rigidly mounted on the frame. The stock 3 is fed to the machine from a bale or spool 4, the wire first passing through a wire straightening means of the rotary typeindicated at 5 and disposed in the housing 6. The wire is drawn through the straightening means by the continuously delivering coacting feed rollers I and 8,-the roller 8 being carried by the swinging bracket 9 pivoted at In and tensioned by the spring H on the rod-like support l2 arranged through the end of the bracket and having a spring tensioning nut l3 on its upper end. This bracket, see Figs. 1, 2 and 3, carries the driven shaft l4 for the upper feed roll. This shaft is provided with a pinion l5 at its rear end meshing with the pinion IS on the shaft ll of the lower feed roll. This shaft I! has a beveled gear l8 meshing with the beveled gear If! on the cam shaft 20 disposed in suitable bearings at the rear of the machine.

The machine illustrated has an individual driving motor 2|, the shaft 22 of which has a pulley 23 connected by the belt 24 to a pulley 25 on the stub shaft 26 which is in turn provided with a pinion 21 meshing with the driven gear 28 on the cam shaft 20. The motor-shaft 22 has a pulley 29' connected by the belt 30 to a pulley 3| on the rotary straightener 5, see Figs. 1 and 2. The driving belt 24 is of the multiple type.

With this arrangement the feed rolls are continuously driven advancing the stock until the front end thereof comes into contact with the stop 32 alined therewith, see Figs. 1 and 31. 'While the frictional engagement of the feed rollers with the stock is such as to positively advance it against the stop, the rolls slip during the period in which the stock is in position shown in Fig. 31, that is, with its end in engagement with the stock.

When the stock has reached this position it is cut off by a cutter comprising the shear block 33 having mounted on its front side the shear plate 34 to which the stock is advanced through the quill or guide 35. The cutter 35 which coacts with the shear plate is adjustably mounted in the reciprocating cutter head 31 mounted on and reciprocating with the slide 33. A suitable way 39 is provided for this slide, see Figs. 1, 4 and 5.

The cutter blade 36 is clamped in its holder 40 in the cutter head by means of the clamp 01: holder 4|. An adjusting screw, 42 is provided for adjusting the blade longitudinally.

The cutter head is mounted for transverse ad- .iustment on the slide and has a slot 43 receiving the clamping bolt 44 as best shown in Figs. 4 and 5. This provides for very easy and accurate adjustment of the cutter. The shear block 33 is also mounted for adjustment and provided with a slot 45 receiving the clamping bolt 46, see Fig. 4.

When the wire is fed from the guide 35 it is delivered between the supporting bar -41 and the feed bar 48, the latter having a downwardly facing longitudinal slot 49, see Figs. 5 and 6. When the cutting mechanism described severs the stock the resulting work blank is supported within this slot or between the feed bar and its coacting support, see Figs. 5 and 6. The severing movement of the slide 31, however, continues until the work is discharged upon the. rests 5|, dropping in front of the grooved rollers 52 disposed at the ends of the forming mechanism and upon the shoulders-'53 of the former arms 54, which are positioned in cooperative relation to the form block or plate 55, see Figs. 9 and 10.

The form plate is of suitable size and shapeto correspond with the body portion of the hanger which is to be formed thereon.

The former arms 54 carry the formers 55. which coact with the formblock, bending the arms of the hanger around the form block. -The from plate 55 is mounted on the under side of the supporting plate 51 which is mounted upon the The purpose of thus mounting the form plate is to '35 shouldered upper ends of the fixed posts or shafts 58 supported on the bed of the machine.

permit the work to be ejected downwardly through the bed or frame of the machine.

The former arms 54 are pivotally mounted on these shafts 58 and provided with pinions 59 coacting with the racks 60 for actuating the former arms, see Fig. 9. The hubs of the former arms rest upon collars 6| on the shaft or post 58, the top supporting plate 51 holding the parts in proper assembled relation. The hubs of the formerarms are provided with cammed clamping members 62 which cooperate with the front side of the form plate in gripping the wire adjacent the ends of the form plate during the flnal forming of the hanger upon the form plate.

When the stockis discharged from the cutter the former arms are in the position shown by full lines in Fig. 8. This discharging position is momentary, and it will be noted by referenceto the actuating cam 64 for the cutter head that the actuating ratchet 65 of the cam groove 56 is embraced by a relatively small portion of the circumference of the cam so that the-feed bar 48 is quickly returned to its receiving position. As soon as the longitudinal slot or groove 48 is brought into register or alinement with the wire guide 35 the feeding of the wire is resumed.

The racks 60 for actuating the former arms are actuated in unison from the cams 61 on the main cam shaft, one of these cams being on the face of the gear 28 through which the shaft 20 is driven. These cams are formed with a considerable dwell portion 63, see Fig. 9; the purpose being to hold the former arms in their fully actuated position during the .twistingand hook j forming operations. 7

The formers 56 areadiustably mounted. upon the former arms, adjusting screws 63 being-prosubstantially longer than the other end 84, thus general triangular shape, is provided with a cen-.

tral tongue or projection 12 at its apex, which coacts with the conformed end portions 18 of the formers in providing the hanger, designated generally by the numeral 15, Fig. 37, with a loop 18 at the apex of the shank 11. This tongue further coacts in holding the ends of the wire during the twisting operation.

The formers have wire receiving grooves 18 in their inner faces and in their ends, see Figs. 16 and 17. The. outer portions 18 of these grooves in the ends of the hangers are of such size as to permit twisting of the wire within the groove and whileit is firmly clamped in the grooves 18 upon the form plate and its tongue 12'.

The rollers '52 are positioned at the ends of the guides 88 and M which have undercut or grooved faces 82 receiving and guiding the ends of the stock as they are swept around by the closing actuation of the formers. The rollers 52 are positioned at the ends of these guides, and inasmuch as the ends of the stock project beyond these rollers, as the stock is delivered to forming position, initial bends or angles are formed in the armsof the stock as the ends are drawn around these'rollers and guided thereby into the guides 88 and 8 I, see the several positions of the parts indicated in Fig. 8.

The bends formed in the arms of the stock are approximately right-angled bends as shown in the first dotted position in Fig. 8 so that as the work is carried to the completely formed position shown in that figure the ends are given a final set or forming operation as they are clamped upon the form and upon a tongue and brought into parallel relation as shown in Fig. 35. It willbe observed thatone end 83, see Fig. 35, is

providing stock for the hook of the shank. The position of the stop 32 determines the length of the longer arm of the shank.

To operate the feed bar 48 one end is engaged .as described with the cutter head 31, the feed bar having a lug 85 engaging a recess 88 in the head, see Figs. 5 and 6. The opposite'end of the feed bar is actuated in synchronism'by means of the slide 81 having an overhanging arm 88 to which the bar is secured, see Fig. 80. rue slide 81 is actuated by a cam 88, the cam groove 88 of which corresponds to the cam groove of the cutter actuating cam 84. With this arrangement of parts the stock is accurately positioned relative to the form block and theformer arms, the swingi g movement of the former arms bending the ends of the stock and carrying them into the guides, as stated, and holding them around and upon the form block.

Toprovide further security in the retaining engagement of the guide 8| with the long arm of the shank, the guide is provided with a spring 8I which overlies the path of the wire, see Fig. 8.

This insures the proper guiding ofthe shankends of the stock to the'twister. During the latter part of the stroke of the forming arms, the clamping member 82 on the former arms securely grips the work and-prevents its sliding movement as the final forming stress is applied thereto.

In order to provide adjustment for the throw of the former arms the journals 82 o; the cam engaging rollers 88 are eccentrically'disposed relative to their supporting studs 84. These supporting studs are rotatable in the racks and are secured m adjusted position by means of the screws 85 engaging the split ends of the rack, see Fig. 9.

mounted on opposed pivots IM and lying, when in advanced position, so that the arms of the shank are swung between them during the final closing movement of the forming members. The faces of the jaws have longitudinal slotsl82 at the outer ends of the jaws adapted to receive the wires when the jaws are closed thereon, thereby engaging and holding the wires in parallel relation with the jaws.

To facilitate the guiding of the long arm of the shank into the jaws, the pivots I8I are provided with beveled heads I83, and as a further guide means thetwister head 88 is provided with a forked guide I84 projecting between the inner ends of the jaws. The jaws are urged to open position by means of the spring I85. They are closed upon the work by means of the wedgeshaped reciprocating cam I88 secured to the end of the push rod I81 arrangedlongitudinally .through the shaft 81. This rod is actuated from the bent lever I 88 pivoted at I88 and suitably I connected to the end ofthe push rod at one end,

the other end of the lever being operatively associated with an actuating cam 'I I8 on the cam wheel III.

It will be noted that the cam I I8 is open at'its ends, and to insure the roller II2 on the lever member III, which is provided with a cam groove II1 ooperating with a roller I I8 carried by the stud II 8 projecting from the carriage.-

The rack 88 is operated in proper timed relation to the hanger forming operations and the hook. formingmechanism, the actuating means comprising the lever 218 pivoted at I28 and slotted .to engage the pin I2I on the lower end of the rack which reciprocates in a suitable sli leway or guide, the lever being actuated by the cam I22 having a cam groove I28 in the face thereof and receiving the roller I24 on the lever 2I8. The cam groove I28 is provided with an adjustable ratchet I25 located at the end of the portion I28 of the cam groove which actuates the twister to twist the shank. The purpose of this is to compensate for the slight tendency of the twisted wires to reactor untwist as a result of the twisting stresses placed thereon.

As the roller passes from this lift it imparts a slight reverse movement to the twister shaft and at this time the carriage is retracted, withdrawing the twister from the path of the hook former.

While the twister carriage is in retracted position the hook forming head I21 is actuated to operative position and rotated to form the hook I28.

The twister head is carried by the shaft I29 rotatively mounted in the vertical bearing I 30 and provided with an elongated pinion I3I. The

hook forming head I21 is provided with a circular form member I32 disposed off center relative to the head and a cooperating bending roll I33 acting as the shaft is rotated to wrap the end of the shank around the form, the form I32 at the same time swinging to centrally position the hook as shown in Fig. 22, that is, to bring the hook into a balanced position relative to its shank. The roller I33 is preferably grooved to minimize the lateral slipping of the work.

When the hook forming head is advanced to work engaging position the circular form block and the forming roller are in the position shown in Fig. 21. The shaft I29 is then rotated to hook forming position shown in Fig. 22 and the shaft is then retracted. The shaft I29 is rotated by means of the segment I34 pivoted at I35 and having an arm I36 engaging the peripheral cam groove I31 in the cam member I38 on the shaft 20. This cam groove is so conformed that the hook forming end is rotated in its advanced or work engaging position; it is then retracted and rotated, in the opposite direction to initial position. 4

The reciprocation of the head is effected through the bell crank lever I40 pivoted at MI and provided with a roller I42 coacting with the cam I43 on the periphery of the cam member I30. The lever I40 is controlled by the cam I43 on the cam member III, this being preferably shaped to synchronize the reciprocating movement of the hook forming head with its rotative movement and the reciprocating move ment of the twister head. A spring I45 holds the roller I42 into engagement with the cam member. The elongation of the pinion I3I permits the rotative' actuation of the shaft I29 as described at the ends of its stroke.

The form plate or block 55, as stated, is mounted on the under side of the support 51 so that the completed hangers are discharged downwardly through the bed of the machine. The work ejector consists of a crosshead I46 mounted on the reciprocating plunger rod I41 disposed centrally at the front of the machine, the crosshead having a pair of end knock-outs I48, a central knock-out I49 and a rear knockout I50. These are supported for vertical ad- Justment in the crosshead, set-screws I being provided for securing them in, their adjusted positions. When the crosshead is in its raised or normal position the lower ends of the tappets or knock-outs are above the work: As the crosshead Is lowered the work is stripped from the form plate and, as stated, discharged downwardly through a central opening in the bed of the machine to achute or guide, not illustrated. The tappet I50 is forked at its lower end to embrace the shank, see Fig. 26.

This crosshead also carries a series of stock positioning members or pushes I54 disposed in alinement and reciprocating at the front of the bar-like work rest 41 so that when the severed piece of stock is discharged by the feed bar 49 it is positively carried down upon the positioning supports as described. The details of the work ejector and stock positioning means are illustrated-in Figs. 2428, inclusive.

The plunger rod I41 is actuated by means of apron-like guard I19 is provided for the the lever I15 pivoted at I16 and controlled by the cam I11, see Fig. 23. A guard I18 is provided for the crosshead, see Figsl 1 and 23, and an pinions 59. 4

This arrangement permits substantially continuous feed of the stock and the finished work is discharged without necessitating retraction or positioning of the operating parts other than is necessary in their forming function and to receive the stock.

In Fig. 33 I have illustrated by chart or diagram the cycle of movements of the several coacting elements of the machine, these elements being illustrated by concentric circles and the period of their functioning relative to the other parts being shown by full lines. By reference to this diagram it will be noted that the wire fed, indicated by the line I55, is-interrupted but a relatively short period.

The first forming step is indicated by the line I56; the twister jaw grip is indicated at I51; the succeeding twisting is indicated at I58, and the succeeding twister tension release is indicated at I59. Thetwister jaw release is indicated at I60 and the twister slide retraction is indicated at I60. The next step, the movement of the hook former into work engaging position, is indicated at I62; the hook winding or forming is indicated at I63 and the succeeding hook former tension release is indicated at I64. The

.hook former retraction or up movement is indicated at I65. The left or return movement of the twister jaw is indicated at I66 and the former return at I61, followed by a stripper down or discharge stroke I68. During this stripper down stroke the cut-off I69 in or work stroke and I10 out stroke occurs. The stripper up stroke I1I occurs during a portion of the first forming stroke. It will be noted that there is some overlapping in the operation of these various elements but they are synchronized with the purpose of securing maximum use.

My improved wire working machine is of verylarge capacity, results in auniform product, and requires a minimum amount of attention. The parts are so formed and arranged that the stress thereon in operation is minimized, which results in durability.

I have not attempted to illustrate certain modifications and adaptations which might be desirable for particular work as it is believed that this disclosure will enable those skilled in the art to which my invention relates to embody or adapt the same as maybe desired.
